Is there any built in flying pathfinding in UE4?

is there any progress on the Aerial Nav Mesh?

If not I will be looking at building my own and could share results. Could you provide suggestions on what you would recommend as far as overriding Recast or what should be reused and leveraged and what should be written originally? I can’t find many resources on working on the NavMesh, any help getting going would be appreciated!

Thanks!
